.TooZZ when?, fina-y conce/ni.:

Be it known that` I, Irvine" L. Kennen, citizen v ot Russia, but havingl declared my` intention oft `becoming a citizen ot the United States, `residing'.at New York city, borough oit lrooklyin in` the4 county et Kings and State ot New York', have invented certain y new `and useful Improvements in` Salietyldlindow Constructions of which the following); is a speciiication.`

Y This inyention relaties to building; con-A structions `and has particular reference to window mechanism of the usual vertical slidingsash style.V

Among the objects ot the invention is to provideimproved means for giving access to the outer surfaces of `window sashes, tor cleansing, polishing; or` other` like purposes, without..requiringthe person to go orreach beyond the plane of` the window, thereby making it sate and convenient for eachentiresash to befcleansed and polished while the operator is stationed entirely within the room.` I am aware that` structures for this general purpose have been proposed heretofore, but amongv the objects I attain are the following: Tomake it easy for both oI two co-operating sashes to ybe manipulated readily in the, manner already stated, means beinpiprovidedto disconnect yone ot the'sash" cords trom each sash so `asto permit the window sash to .swing or be drawn inward "around the opposite edge thereot as an axis `for cleansing `or removalv and then `for it to be returned and the sash cord reconnected botheasily andquickly; to provide means for removing the` upper and normally.

outer sash whether the lower sash is removed from the window or not, an expedient notv heretofore provided for so` tar as 1 am aware;` also to provide means tor removing' easily both sashes 'from the` wmf dow tor maxn'num ventilation or other puri poses, the disconnecting means for the sash Cords beingbo th .operated simult aneously by a single simple mechanical movement,` and l provide meansfalso ttor locking both window `sashes` to each other in such. a manner as to make .it impossible for` either sash to be moved, the lockingmmeans being;` hidden within the window trame.k

llitlrthe foregoing and other objects in viewthe invention consists in the `arrangement and combination. ot parts hereinafter described `and claimed, and while the inventionisnot restricted to the exact de`- tails ot' construction disclosed or suggested i herein, still ttor the purpose oit illustrating a practical embodiment thereof reference is had to Athe accon'ipanying. drawings, in which like reference characters designate the saine parts intheseveral views, and in whielii Figure 1 is atront elevation ofimy im`` proved window construction as viewed roni the inside, the window 'frame being` shown open togiveaccess to the mechanism, and portions being; brokenaway at the top.

Referring new more specifically to the "drawingsl show a` window tramehaving; right andllett sides 1() and 11, a top 12 and a bottom or sill 13. The stiles and 11 are made `hollowas usual for theaccommodationiolithe'vertically slidable sash weights 111 conn'ectedrby cords or the like 15 tothe respective upper andlower sashcs 16 `and 17. AccordingI to the showing the weights ttor the right side of the Lwindow operate over simple pulleys 18, while those at the left side operate overdouble pulleysv 19fjournaled in. brackets 2O which extendl tar enough laterally ftoguide the weights to opera-te, in. plane Vfarther 'from the sashes than usual. The counterweightinpeliect oi theweights 14- on the several sashes is as usualdilring.the up and `down sliding movements ot the sashes. `Within the top 12 of the trame is `arranged a cap 21 connected at its ends to a pair of arms 22 and 28, the rear ends ot which are pivoted at 24, the cap being movable upward by impact ot the top ot the lower sash 17 for the purpose ot permitting free forward removal ot the upper sash at the bottom ot the window in a manner soon to be described. rlhis upward movement of the cap 2l is resisted by means of a weight QA! attached to the arm 23.

The sash cords l5 are all detachably connected to the vertical side rails of the ro` spective `sashes in order to permit the manipulation of the sashes, either 'for cleansing` or ttor removal thereof entirely from the window trame. The cords at the ri ght side o't the window are provided each with a clip 25 having the cord secured within a stem 25a thereof and having at or near its lower end a T-hea-d 26, the longer axis ot which is parellel to the stem. The sash in its adja` cent edge is provided with a recess 27 over which is secured a socket plate 28 having a transverse key hole or slot 29 to receive the head 26 therethrough when y the clip is turned at right angles to the window sash or its normal position. After the head is thus passed into the 4socket and is swung; with the stem upward the head is interlocked in the socket and thus the cord is reliably secured in operative position. The cords obviously may be removed easily by a re` vcrsal. ot the aforesaid operation when de` sircd to detach entire-ly the sashes -from the window.

At the opposite or left side of cach sash is provided as shown a recess 30 in which is litted a .metallic socket member 3l havingl an open top and open side, the side walls ot the socket beiner provided with open ended tapered slots 32, the opening thereo't being; downward and flush with the side edge ol' the window sash and the closed upper' lend oi each slot forming` a seat 'tor a laterally projecting lucr 33 'formed on or carried by each side oit a clip Bit For the cord l5 at that side. It will be understood troni Figs. 4- aud 5 that the two laterally projecting;` lugs 33 are adapted to be received into the socket piece 31 through the lower open mouths or ends ot the slots 32 and be guided upward into their seats in the side walls oit said socket piece while the weight attached to the cord thereof acts to draw the saine normally upward and hold it in its place. The lower end ot' the clip 34; consists oit a hook 35 the point ol which projects upward and. outward but still within the plane oit the side edge ot the window sash in normal position. These clips 3ft and co-operating parts as just described in detail are provided for both the sashes. See Fig. 1.

Vithin the stile l1 and located. between the plane of the weights and the wall 86 constituting the bottoms oi" the channels in which the sashes are guided is located a casing,` 37 extending upward alom;` the lower portion of the window trame and containing;- within it the principal parts of the actuating; or detaching mechanism. This casingand the parts associated therewith are normally hidden from view within the side piece of the 't 'ame and access thereto is had when desired by means of a door 3S adapted to swing forward and away from the window as shown in Fig l. In any suitable part of the casing; 8T is journaled around a horizontal axis a shait 39 journalcd in brackets `t() and having` on its forward end an actuating,r lever' tl or its equivalent projecting normally upward.

An actuator dog` Lit?, projects through a slot 43 in the wall of the casing and a space or slot 44 in the wall BG and is designed to be given both sliding and tilting nuwenzent with respect to a fixed pivot pin 415 extending through a slot /l in the den'. rlhe inner end et the dogg,l is pivoted at /ll' to an arm at; lixed to the shaft 39 and constituting' with the lever llt a bell crank. The arm projects normally downward and slightly away t'rom the window sash, the pivot 457 beinzgr normally below the pin The outer end ot the dog consists of a downwardly projecting; hook i9 which lies normally close outside the vertical plane ol the edge of the window sash and close above the hook 35. When it is desired to detach either clip 84 from the window sash, the sash being adjusted lo a proper elevation for this purpose, the operator simply swings open the door 3S, grasps the lever L.tl and swings it downward to the lett, and causes thereby the dog; to be projeeted outward sliding along the pin 45 and ultimately in a clockwise partial rotation around the pin, the hook 4:9 passiingr first outward over the hook and then downward into engagement with the hook 3&5 and so serving; in the latter' part ot the mover-,nent ot the actuator to carry the clip 3ft downward and the lugs 33 out ot their seats, the two hooks 35 and 49 remaining` in interlocked enrieclnent while the lever L'tl rcmains in its down position. lt will be uuderstood that the actuators `for' boil sash clips fl-flY are operated simultaneously so that either or both ot them will detach the clips 3l dejfiendirur upon the location ot the window sashes at such time.

The guide channels above referred to in which the sashes slide up and down in the usual manner include on the right side as shown ilront, rear, and middle strips ad 5t. and 52 lixed as usual to thC window traine, 0n the other side, however, the strips 5o and 52, particularly adjacent to the lower halt of the window trame, are movable out of normal position toward or into the hollow side wa l ot the window trame, as shown 'n Fig. 6, to permit the sashes to be removed. inward after he cords are detached thereitin `cranks p Leedses from justfdesciiibed. j nysuitable means niay provi ded drawing 'these movable guides out o'f tlie`\vay,l`and to 'this'end l 'show nieclianisjgn yas follows `FB are twb Vbell ""lvoted4 on` vertical pljvots 5ft aid movable siiiiiiltaneolis'ly throtlfg'h arcs of V- cles ai'drind such pivblt's bty iiibttns of a rod end of'tlils rodhas a knob 55" piojectiiirgv iii fro 'itof the casing" 37 iiidwitliiii l'oiive'nient of theA `operator' afterhe has dperated the actuator' lcv-ei' 41. 'A ptiir of liiiks 5i' and at itsbtliei' di' ,d-uteii end itis pivoted a't lyto a braclnetbr plate 6() secured to the iiidi'abl'e strip. l In the normal position 'of tlic `hf'tiides as shownin'l? 2, the links 57 aiid adjacent oi' fijo'rit portions of the bell cranks lie ii" substantially a" straight line, thereby lock j' the strips iii' hormal"pr` jects/d` sash li'lding postin and the rod 55 with its khob bein@ at this time forrfvard. This willbe understood `from Fie'. (i which shfivf's the Ie'iiides witlidi'awii fr normal position and the bell cranks sosivuligfw" bi'ea'k the ldck j'tist mentioned.' A simple push `rearward, however, of the rod will swinj'e the bell' cranks abound their pivots and d raw the guides to the position shown in 6. While these guide strips are (lll from the .disconnecting means.

shown coupled for simultaneous shifting,- movement yinto and out of position, it is obvious that the `mechanism might be arranged so that they might be operated in dependently if preferred.

From the foregoing specilic description of the mechanism 'the inode of operation may be brieiy summarized as "follows: lith the window sashes in their normal position and guided for the usual sliding movement up and down if it be desired to polishthe outer surfaces, the operator if he wishes to` act upon the sashes one at a time which is the usual course, may open the door 38, actuate the lever -ll as described and so detach the clip Blfrom the left side `ot the lower sash and then push rearward the rod 55 to remove the guides from sash holding position. The upper sash may have been lowered so as to be in position to be removed subsequently in its turn and if so its clip 3ft will have been removed from the socket 31 at the same time. Or if preferred the upper sash may have been left elevated and so remote A The operator then grasps the lower sash and4 lifts or swings it inward around the right guide channel as a pivot and rests it upon a pad or cushion 61 which may be provided if de sired to prevent the marring of the. windowsill, and to the top of the sash a rod 62 located normally adjacent to the guide 50 may be hooked to the hook 63 so as to relieve the dperator from holding the sash in open position".` The sasli is` then" suspended s'ubsttiiitiallyv as slioivn iii tlie dia" 'rain of Fig. rl'Min such pbsitiion that the operator may while standingy erect iii'ithintlie room polish the outer surface di the paire. After the glass is poli ied the sashis returned t`o its noifnial position and theclip 3a is co'iin tedag'rin in place in Fig. 5 and then this lower .ish may be 'slipped up along' the guide channels ai` endiiglito lift the cap 2.1 and so clear the top 'of the upper sash which in tiii'h will be brtlught forward after its' clip Sil` is detached for cleansing as just described. The same rod 62 acti-ng upon a` hodk '63 at the top of the upper sash will o actasbeflbrc described) For maimum ventilation di' Vo'tlierwisc both sashes may be rfc moved readily from the window by swing'- ing them forward asjust stated and then disconnecting' the clips 25 as before described, leaving' the sashcs free to be lifted down from the window; y

The provision of the hollow windoi'v frame lll4 and access thereto through lthe door 38 renders it feasible to employ a pecu'liarl sash lock for locking' the sash'es from relative inovenient especially when'bth are closed as in Fig. 1l. This locking mecha nism comprises a horizontally movable keeper 64 having' point or tongue members project-able into a pair ot holes or :notches 65 and 66 formed inthe adjacent portions of the upper and lower sashes respectively. The keeper is rigid and therefore both sashes are positively locked from relative movement. To unlock the window the operator simply projects his hand within the hollow frame and withdraws the keeper from holding positiom'until a stop GS is struck, a manipulating handle G7 being' provided for this purpose.

I claim: i

l. The combination with a window frame, a sash slidable up and down therein, and counterweights connected to the sash, of a connection for one `of the counter-weights ico including a socket piece counter sunk in a cause the same `to have'a reaching' and` sweepingmovement into engagement with the clip.

2. The combination with a window frame, a pair of relatively slidable co-operating' sashes movable up and down therein. and counterweights connected to the respective sashes, of manually operated means at one side of the window sashes for simullai'leously disconnecting both counterweight conneetions from the adjacent side of both sashes, the mechanism for detaching both connections simultaneously including a rock shaft, a pair of slidable and tiltable dogs having hooks for engagement directly with the weight connections, and a pair of arms extending from the rock shaft and pivotally connected to the ends of the dogs remote from the engaging ends thereof.

3. In a window construction, the combination with a frame having a hollow side, a pair of sashes slidable up and down therein relative to each other, and guiding means for normally holding the sashes in sliding position, of means manually operable from within the hollow vside of the frame for withdrawing the guiding means simultaneously from the same side of both sashes to permit said sashes to be brought inward from the frame, said means for withdrawing the guide means comprising a pair of bell cranks mounted to swing around parallel axes, a rod connected to both bell cranks for swinging them simultaneously, and loose jointed connections between the bell cranks and the guide means, substantially as set forth.

-l-. ln window construction, the combination with a frame, a pair of sashes movable relatively up and down therein, means Ato disengage the sashes singly from the frame for removing the same inward therefrom, and means at the top of the frame to permit one of the sashes to move upward above its normal run in order to clear the other sash for the removal of the latter while the former stays in the frame, said means including` a horizontal cap member, a pair of arms connected thereto and movable around a horizontal axis at the rear of the cap, and means connected to the cap resisting the movement thereof out of normal position.

5. In a window construction, the combination of a frame having removable guide means, a sash slidable' along said guide means, means' for removing said guide means to allow the sash to be swung out of the plane of said frame, a hook upon said sash and means attached to said frame cooperating with said hook to retain said sash in substantially fixed position relatively to said frame after being swung out of the plane thereof.

In testimony whereof I aix my signature.
